Abstract (en)

[origin: EP2685083A2] A machine (100) comprising an engine (102) operable at various engine speeds including a resonant frequency engine speed. The machine comprises a hybrid motor (118) operatively connected to the engine, the hybrid motor being adapted to apply power to the engine. An electronic control module (124) is configured to control the hybrid motor to apply power to the engine until at least a time when the engine speed exceeds the resonant frequency engine speed.
